Your dish is called a jacket potato if I understand you right. What I like to do is boil rice then mix it with peanut butter and sriracha and just eat that like it is.

Bun, brat, mustard, sourkraut. If there is a pack of malt vinegar in the drawer, that too.

I blend 2 eggs with a banana, and I fry it as if it's a pancake, with butter. It doesn't hold together, so it keeps coming out as if it's weird scrambled eggs. But it's delicious, the healthiest kind of pancake (with a drop of raw honey afterwards).

It's bending the rules, since it's a camping meal, but I have made it at home, too, since it makes a great depression meal. I got it from backpackers, who I'm pretty sure got it from prison inmates:

The Ramen Bomb.

Cook a crushed up packet of instant ramen noodles, maybe with a little more water than usual. Add like half a packet of instant mashed potatoes. You can also add a protein, like... chopped up Spam. Maybe some hot sauce or other fixings if you're feeling fancy.

I hated how much I enjoyed it. Granted, that was when I was really tired and hungry, but that hit the spot.

Also, I've heard meals like the ones in this thread affectionately referred to as "glop," by a fellow glop-enjoyer.

Had me until the yeast.

Raw tagliatelle. I love picking it apart and eating it, it has a satisfying crunch, especially when pieces directly overlap, but I'd be silly to just up and serve a plate of raw tagliatelle to someone 😂

Grits with canned tuna.

Grits with chili paste, fried egg, pork fu.

Sandwich of sardines and mayonnaise and raw onion.

OP, my sweet potato lunch is a Stokes Purple one frozen then baked, topped with goat cheese, pepitas, olive oil and fancy salt. I don't even like sweet potatoes but like that there's enough salty/sharp stuff

Raw jello powder, add a dribble of water to make part of it a super thick paste.

Blue cheese, and sweet condensed milk dip with tortilla chips.

Note: I might have more, but just woke up from a nightmare and its 2:30am. Will try to come back later.
